Normal Metal Model

The Normal planar metal loss model is used for most circuit metal. It models the conductor as a  zero-thickness sheet of metal. You enter the metal thickness and the Current Ratio, and chose how you will specify the third field: Conductvity, Resistivity, or Sheet Resistance at DC by selecting an entry from the Specify Using drop list. These three values are used to determine the frequency dependent surface impedance of the metal.

For more information on the current ratio, see Current Ratio.

Note: Metal thickness is used only in calculating loss; it does not change the physical thickness of metalization in your circuit. The metalization in your circuit is still modeled as zero-thickness. To model thick metal, see the Thick Metal Model type.
